A 70 kg window cleaner uses a 20 kg ladder that is 5.4 mlong. He places one end on the ground 2.2m from a wall, rests the upper end against a cracked window, andclimbs the ladder. He is 3.5 m up alongthe ladder when the window breaks. Neglect friction between theladder and window and assume that the base of the ladder does notslip.
(a) When the window is on the verge ofbreaking, what is the magnitude of the force on the window from theladder?
N
(b) When the window is on the verge of breaking, what is themagnitude of the force on the ladder from the ground?
(c) What is the angle of this force on the ladder?
° (above thehorizontal)
